Note 865 — Chapter VIII · MOTTE-CASTLES IN NORTH WALES
Reading edition
Mr Davies Pryce has suggested that the Hen Domen, a very perfect motte and bailey within a mile of the present castle of Montgomery was the original castle of Montgomery, and that the one built by Henry III. was on a new site. This of course is quite possible, but I do not see that there is sufficient evidence for it. See Eng. Hist. Rev., xx., 709.
